Nested "for" loops

This is a discussion on Nested "for" loops within the C Programming forums, part of the General Programming Boards category; Is there a limit on how many for loops I can nest or would it complicate the program?...

Both the translation and execution environments constrain the implementation of
language translators and libraries. The following summarizes the language-related
environmental limits on a conforming implementation; the library-related limits are
discussed in clause 7.

— 127 nesting levels of blocks
— 63 nesting levels of conditional inclusion
— 12 pointer, array, and function declarators (in any combinations) modifying an
arithmetic, structure, union, or incomplete type in a declaration
— 63 nesting levels of parenthesized declarators within a full declarator
— 63 nesting levels of parenthesized expressions within a full expression
— 63 significant initial characters in an internal identifier or a macro name (each
universal character name or extended source character is considered a single
character)
— 31 significant initial characters in an external identifier (each universal character name
specifying a short identifier of 0000FFFF or less is considered 6 characters, each
universal character name specifying a short identifier of 00010000 or more is
considered 10 characters, and each extended source character is considered the same
number of characters as the corresponding universal character name, if any)14)
— 4095 external identifiers in one translation unit
— 511 identifiers with block scope declared in one block
— 4095 macro identifiers simultaneously defined in one preprocessing translation unit
— 127 parameters in one function definition
— 127 arguments in one function call
— 127 parameters in one macro definition
— 127 arguments in one macro invocation
— 4095 characters in a logical source line
— 4095 characters in a character string literal or wide string literal (after concatenation)
— 65535 bytes in an object (in a hosted environment only)
— 15 nesting levels for #included files
— 1023 case labels for a switch statement (excluding those for any nested switch
statements)
— 1023 members in a single structure or union
— 1023 enumeration constants in a single enumeration
— 63 levels of nested structure or union definitions in a single struct-declaration-list
